Which of the following species do not exist?
- A \(\left[\mathrm{SiF}_6\right]^{2-}\)
- B \(\left[\mathrm{SiCl}_6\right]^{2-}\)
- C \(\left[\mathrm{GeCl}_6\right]^{2-}\)
- D \(\left[\mathrm{SiF}_5\right]^{-}\)
Answer & Solution
Correct Answer
(B) \(\left[\mathrm{SiCl}_6\right]^{2-}\)
Step-by-step Solution
Detailed explanation
\(\left[\mathrm{SiCl}_6\right]^{2-}\) does not exist. The chlorine atom is much larger than fluorine which does not allow the six \(\mathrm{Cl}\) atoms to surround the silicon due to repulsion between \(\mathrm{Cl}\) atoms. Hence, due to interelectronic repulsions between…
